- Copper-Catalyzed Tandem Cross-Coupling/[2 + 2] Cycloaddition of 1,6-Allenynes with Diazo Compounds to 3-Azabicyclo[5.2.0] Ring Systems
-
An unprecedented copper-catalyzed tandem cross-coupling/[2 + 2] cycloaddition of 1,6-allenynes with diazo compounds was reported, chemo- and regioselectively providing 3-azabicyclo[5.2.0] frameworks in moderate to excellent yields under mild reaction conditions. Moreover, the products readily convert to highly functionalized quinolines via oxidative radical rearrangement.

- One-Pot Access to Benzo[a]carbazoles via Palladium(II)-Catalyzed Hetero- and Carboannulations
-
A Pd(II)-catalyzed direct synthesis of benzo[a]carbazoles has been achieved through aminopalladation of alkynes, followed by intramolecular nucleophilic addition of the generated carbon-palladium bond to a tethered cyano/aldehyde group. Compared to literature procedures, this synthetic approach is operationally simple, uses simple substrates, and offers a fast intramolecular assembly resulting in the direct synthesis of benzo[a]carbazoles in which a wide variation of substituents at different sites is well-tolerated, leaving enough opportunity for diversification.

- Single bifunctional ruthenium catalyst for one-pot cyclization and hydration giving functionalized indoles and benzofurans
-
Chemical equation Presented Bifunctional is more than twice as fun! At low loading, catalyst 1 (see scheme) can form two important heterocycle classes, apparently by attack of XH on a vinylidene intermediate. Aza- and nitroindoles can be formed, and all N-protecting groups tested (alkyl, allyl, sulfonyl) were tolerated. The newly formed ring can be deuterated in one step, and for substrates with two terminal alkynes, cyclization can be followed by hydration, making this catalyst uniquely versatile.
